Width limiting device for roads

Abstract

The invention discloses a width limiting device for roads, and relates to the technical field of road construction. The problem that the width limiting distance is not easy to adjust after a width limiting pier of a road is placed is solved. The device specifically comprises a base and a shell, a top box is fixedly mounted at the top end of the shell, two mounting grooves are formed in the two sides of the shell, limiting sleeves are fixedly mounted in the mounting grooves, a sliding groove part is formed in the top end of the base, a buffer mechanism is slidably mounted in the sliding groovepart, and the shell is fixedly mounted at the top end of the buffer mechanism; and telescopic rods are inserted into the limiting sleeves. The width limiting part is mainly composed of the width limiting plate mechanisms on the two sides, so that the phenomenon that rearview mirrors are scratched and damaged when cars and other vehicles pass can be avoided; and meanwhile, when the vehicles directly impact the surface of the device, the buffering mechanism in the device works to drive the upper portion of the device to retreat, so that impact on the vehicle is buffered, and the damage degree ofthe collided vehicle is reduced.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a road width limiting device. Background technique [0002] Urban roads lead to all areas of the city, used for transportation and pedestrians in the city, convenient for residents to live, work and cultural and entertainment activities, and connect with roads outside the city that bear the burden of external traffic. Urban roads are generally wider than highways. To adapt to complex The transportation means are divided into motor vehicle lanes, bus priority lanes, non-motor vehicle lanes, etc. On both sides of the road, there are sidewalks and housing buildings above the road surface, and public pipelines are mostly buried under the sidewalks. Arrange green belts and sculptures to beautify the city. In order to protect the sanitation of the urban environment, it is necessary to reduce dust and noise.

AI Technical Summary

Problems solved by technology

[0003] At many newly constructed road intersections, width-limiting piers will be installed to restrict the entry of large vehicles. At present, most of the width-limiting piers are directly poured with cement, which is a one-time concrete pouring. The width-limiting piers are mainly used to restrict large vehicles. Drive into the crushed road, but it is not easy to adjust the distance of the width limit after placing it, and use a forklift or crane to dismantle it after use, the workload is heavy, and the safety performance is poor during use, and the vehicle hits the width limit at night Shidun reports happen from time to time
